Add 'richtek,bled-ocp-microamp' property to make it chooseable.

The wrong backlight ocp level may affect the backlight channel output
current smaller than configured.

Since v3:
- Refine the description for backlight ocp property.
- Use the enum to list the supported value.

Since v2:
- Change the property name from 'richtek,bled-ocp-sel' to 'richtek,bled-ocp-microamp'.
